SYNTHESIS PROCESS OF POLYOL CARBONATE FROM POLYOLS, CONDUCTED IN USING A SOLVENT SELECTIVE FOR POLYOLS CARBONATES

摘要

THE PRESENT INVENTION RELATES TO A SYNTHESIS PROCESS OF POLYOL CARBONATE, SUCH AS GLYCEROL CARBONATE, FROM POLYOLS SUCH AS GLYCEROL, PROPYLENE GLYCOL OR ETHYLENE GLYCOL AND UREA CONDUCTED IN USING A SOLVENT SELECTIVE FOR POLYOLS (GLYCEROL) CARBONATES. SAID PROCESS COMPRISES REACTING POLYOL WITH UREA IN THE PRESENCE OF A CATALYST, EXTRACTING PRODUCED NH3 AND IN ADDITION IN THE PRESENCE IN THE COURSE OF AT LEAST ONE STEP OF THE PROCESS OF A SELECTIVE SOLVENT FOR POLYOL CARBONATE ALLOWING TO EXTRACT IT FROM THE REACTION MEDIUM. NO SUITABLE
